Why B6266 runs late
Where US DOT attributed the delay minutes on this flight.
crew, maintenance, boarding and fueling, all within the carrier’s control
the inbound aircraft was late, so this flight started late
airspace and airport capacity, including weather-driven flow control
weather severe enough to stop this flight specifically
Share of the delay minutes US DOT attributed to each cause for B6266 on RSW → BOS. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies B6266 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, B6266 pushed back an average of 48 minutes late; when it came in on time or early, an average of 3 minutes late.
Each departure is matched to the flight the same aircraft flew into RSW just before it, using the tail number in the DOT file, 753 of 793 departures in all. A departure is left out when that flight is unknown, was cancelled or diverted, or the aircraft had sat for more than 12 hours. A flight the airline cancelled never left and is not in the count, and one flown by a substitute aircraft is matched to the aircraft that flew it, not to the one first planned.
Against the network at the same turn length
| Share of departures | Inbound landed 15+ late | Left 15+ late after a late inbound | Left 15+ late after an on-time inbound |
|---|---|---|---|
| B6266 | 17% | 42% | 13% |
| Network, same turn | 18% | 85% | 10% |
The schedule leaves a normal turn: enough time to clean and board if the aircraft is on time, little to spare if it is not.
The network row is every flight with a scheduled turn of 45 to 59 minutes. How often B6266’s aircraft landed 15 or more minutes late is about the same as the network’s and, once the aircraft was late, how often B6266 left 15 or more minutes late is lower than the network’s.

From pushback to gate
When it leaves RSW late, does that still matter by the time it reaches BOS?
B6266 pushes back an average of 15.9 minutes late and reaches the gate at BOS an average of 11.4 minutes late. The 4.5 minutes between those two figures are slack the published schedule already carries, which is why a late pushback on this flight does not reliably become a late arrival. It spends 15.9 minutes on the taxiways at RSW, 2.1 minutes longer than a typical RSW departure in the same hour.
On arrival at BOS, B6266 spends 8.1 min taxiing from touchdown to the gate — ground time a connecting passenger sits through before they can even leave the aircraft, on top of however late the flight itself ran. That is about what any arrival at BOS spends on the ground before reaching the gate.
Departure delay is averaged over every pushback and arrival delay over every completed arrival, so the two counts differ by the flights that never reached BOS. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 7,757 departures from RSW scheduled in the clock hour B6266 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at BOS (440,886 flights), not just B6266’s own. More on taxi time.

The hour it leaves RSW
Part of any flight’s record belongs to the clock rather than to the flight. B6266 has one departure time, so this is what that time is worth.
On-time arrival rate. 7,757 departures from RSW are scheduled in the 6 AM–7 AM hour over the period, against 107,483 across the whole day.
B6266 is scheduled out of RSW at 6:00 AM, in the 6 AM–7 AM bank. Departures from RSW in that hour arrive on time 93.5% of the time against 78.8% across the airport’s whole day — the slot alone is worth 14.7 points better before anything about this particular flight is considered.
The two airport figures cover every departure from RSW to every destination, so they describe the slot rather than this journey — the like-for-like comparison against the route is above. Hours are scheduled local, and a number whose schedule moved between banks inside the period has no single hour and is not described here at all. Why the hour matters.

When it goes wrong
The average describes a usual day. This is the day that ruins a connection.
55 min late
against a median of 8 min early
B6266 has an average that understates its risk: a typical arrival is 8 min early, but the worst tenth are 63 minutes worse than that. If the trip has something unmissable at the end of it, the median is the wrong number to plan against.

Other flights on this route
Same airports, same journey, different odds of arriving on time.
| Flight | Airline | On time | Median arrival | Operations |
|---|---|---|---|---|
| B6266 this flight | JetBlue | 79.4% | 8 min early | 806 |
| B62066 | JetBlue | 58.5% | 7 min late | 875 |
Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. B6266 is placed in the same ordering rather than left out of it; the rows around it are the most punctual departures on the route, not all of them, so this is a comparison and not a rank. Schedules change; confirm the departure still operates before booking around this.
Data and methodology
Calculated by FlyerIntel from 806 records of B6266 operating RSW → BOS, published by the US DOT Bureau of Transportation Statistics. A flight counts as delayed when it arrives 15 or more minutes after schedule. Cancelled and diverted flights are excluded from the on-time rate and reported separately. Flight numbers are resolved as carrier plus number plus route, because the same number serves different routes over time.
